More general fixes from clojure.test.check's own suite. - *unchecked-math* on doubles: unchecked-* only wrap integer math; on a flonum operand they're an ordinary float op (Clojure: (unchecked-multiply 1.5 2.0) => 3.0). test.check's rand-double is (* double-unit shifted) under *unchecked-math* and was truncating to a long 0, so every distribution-driven generator (choose, vector, …) collapsed to its lower bound. - (take Double/POSITIVE_INFINITY coll) takes the whole coll instead of throwing on the infinite count coercion (rose-tree unchunk relies on it). - (java.util.UUID. msb lsb) 2-long constructor (the uuid generator), formatted as the canonical lowercase 8-4-4-4-12 string; (Long. n) constructor; BigInteger .shiftLeft / .shiftRight (size-bounded-bigint); number methods now receive args. - A transient (ITransientSet) responds to .contains / .valAt / .count (distinct-collection generators). make test green (+3 corpus rows, 0 new divergences), runtime only (no re-mint).

;; dot-forms.ss — generic dispatch for the `.` special-form / `.-field` desugar.
|
|
;; The analyzer lowers (. target member arg*) and (.-field target)
|
|
;; to a :host-call; the Chez emit routes a non-shimmed :host-call through
|
|
;; record-method-dispatch. This file extends that dispatcher with the collection
|
|
;; arms the interpreter's dispatch-member covers but the record/string base does
|
|
;; not, with this precedence:
|
|
;;
|
|
;; * collection interop wins first — count/seq/nth/get/valAt/containsKey on a
|
|
;; vector/map/set/seq/record (so (. {:count 9} count) is the entry count, 1,
|
|
;; NOT the :count field).
|
|
;; * field access — a "-name" member reads the field (records and maps).
|
|
;; * map member — a stored fn is a method (called with self + args); any
|
|
;; other value is returned as a field.
|
|
;;
|
|
;; Anything not recognized falls through to the previous dispatcher (jhost /
|
|
;; number / regex / jrec protocol / string). Loaded LAST (after host-static.ss).
